ECC v2.0.0-rc.1 Release Name And Plugin Publication Checklist

Snapshot date: 2026-05-18. Canonical repo decision refreshed 2026-05-19 after the public repo rename to affaan-m/ECC; release/package state refreshed 2026-05-26 after the GitHub prerelease and npm next readbacks succeeded.

This checklist is the operator gate for release naming, package publication, and Claude/Codex plugin distribution. It is not a publication action by itself. Run it from the exact release commit before creating tags, publishing npm, submitting marketplace forms, or posting announcements.

Fixed rc.1 Decision

Ship v2.0.0-rc.1 as ECC.

Keep the GitHub repo at affaan-m/ECC.
Keep the npm package as ecc-universal.
Keep Claude and Codex plugin slugs as ecc.
Publish the npm prerelease on the next dist-tag, not latest.
Do not rename the npm package to ecc or @affaan-m/ecc before rc.1.
Treat affaan-m/ECC as the canonical public repo for rc.1 and GA release copy.

Reasons:

ecc-universal is the current working install and package surface.
ecc on npm is occupied by an unrelated elliptic-curve package.
@affaan-m/ecc is unclaimed on npm, but would require a migration plan.
affaan-m/ECC is now the live public GitHub repo.
Claude and Codex already expose the desired short namespace as ecc.

Current Surface Evidence

Surface	Current value	Evidence command	Current result	Release action
Git commit	`67e63e63f9bfd074bd6a21bf6bac71f3dfefa58b`	`git rev-parse HEAD`	Recorded from clean `main` before this ITO-46 evidence refresh	Re-run from final release commit
GitHub repo	`affaan-m/ECC`	`git remote get-url origin`	`https://github.com/affaan-m/ECC.git`	Keep for rc.1 and GA
npm package	`[email protected]` local and registry next, `1.10.0` registry latest	`node -p "require('./package.json').name + '@' + require('./package.json').version"` and `npm view ecc-universal name version dist-tags --json`	Local rc.1 ready; registry `next` points to `2.0.0-rc.1`; `latest` remains `1.10.0`	Keep rc.1 on `next`; do not move to `latest` before GA approval
Exact npm short name	`ecc`	`npm view ecc name version description repository.url --json`	Occupied by unrelated `[email protected]`	Do not use
Scoped npm short name	`@affaan-m/ecc`	`npm view @affaan-m/ecc name version --json`	404	Candidate only after migration plan
Claude plugin	`[email protected]`	`claude plugin validate .claude-plugin/plugin.json`; `claude plugin validate .`; `claude plugin tag .claude-plugin --dry-run`	Validation passed on Claude Code `2.1.143`; full plugin validation has one expected root `CLAUDE.md` context warning; dry run would create `ecc--v2.0.0-rc.1`	Run dry-run tag again from the final commit, then tag/push only after approval
Claude marketplace	`.claude-plugin/marketplace.json`	`claude plugin marketplace add --help`; Anthropic plugin marketplace docs	GitHub repo, git URL, remote marketplace JSON, and local path marketplace sources are supported	Verify post-tag marketplace install/update path after final evidence
Codex plugin	`[email protected]`	`node tests/plugin-manifest.test.js`; `codex plugin marketplace add --help`; OpenAI Codex plugin docs	Plugin manifest passed 54/54; local and GitHub-ref repo marketplace smokes passed on Codex CLI `0.131.0`	Use repo marketplace for rc.1; do not claim official directory listing until OpenAI publishing path is available
OpenCode package	`[email protected]`	`node -p "require('./.opencode/package.json').name + '@' + require('./.opencode/package.json').version"`	Matches rc.1 package identity	Follow npm package publication
Billing claim	ECC Tools selected-target billing evidence ready	ECC Tools billing gate and Marketplace account readback	May 20 selected-target readback and live selected-target announcement gate passed with `announcementGateReady: true`; repeat immediately before announcement	Do not announce native payments until final release/plugin/live URL approvals are green

Required Gate

Run these checks from the final release commit and paste the exact output into a fresh publication-evidence-YYYY-MM-DD.md file before release actions:

bash

git status --short --branch
git rev-parse HEAD
git remote get-url origin
npm view ecc name version description repository.url --json
npm view @affaan-m/ecc name version --json
npm view ecc-universal name version dist-tags --json
node tests/plugin-manifest.test.js
node tests/docs/ecc2-release-surface.test.js
claude plugin validate .claude-plugin/plugin.json
claude plugin tag .claude-plugin --dry-run
codex plugin marketplace add --help
HOME="$(mktemp -d)" codex plugin marketplace add ./
HOME="$(mktemp -d)" codex plugin marketplace add affaan-m/ECC --ref "$(git rev-parse HEAD)"
npm pack --dry-run --json
npm publish --tag next --dry-run
npm run build:opencode
npm run preview-pack:smoke
npm run release:approval-gate -- --format json

If a command is unavailable on the release machine, record the exact error and keep the related publication action blocked.

Publication Order

Step	Action	Required evidence	Stop condition
1	Freeze name and version	Package, Claude plugin, Codex plugin, OpenCode package, `VERSION`, and release docs all say `2.0.0-rc.1`	Any `preview`/`rc.1` mismatch
2	Verify clean release branch	`git status --short --branch` shows only the intended release commit and no unrelated drift	Any unexplained dirty file
3	Verify package and plugin manifests	`node tests/plugin-manifest.test.js` and `node tests/docs/ecc2-release-surface.test.js` pass	Manifest or release-surface failure
4	Dry-run package surface	`npm pack --dry-run --json`; `npm publish --tag next --dry-run`	Missing files, wrong dist-tag, or publish dry-run failure
5	Dry-run Claude distribution	`claude plugin validate`; `claude plugin tag .claude-plugin --dry-run`; marketplace source/help evidence	Validation, tag, or install-smoke failure
6	Verify Codex repo marketplace	`codex plugin marketplace add --help`; temp-home local and GitHub-ref repo marketplace add smoke; OpenAI official directory status recorded	Missing repo marketplace or unverified official-directory status
7	Verify OpenCode package	`npm run build:opencode`	Build failure
8	Regenerate release URL ledger	Live and approval-gated URLs separated in `release-url-ledger-YYYY-MM-DD.md`	Placeholder, private URL, or announcement URL drift
9	Verify GitHub prerelease	`gh release view v2.0.0-rc.1 --json tagName,url,isPrerelease`	Missing URL or wrong prerelease flag
10	Verify npm rc	`npm view ecc-universal version dist-tags --json` shows rc.1 on `next` and latest still on GA/stable	rc.1 lands on `latest` or registry output is unclear
11	Publish/plugin-submit	Claude official submission and Codex repo marketplace evidence recorded	Form not submitted, listing not visible, or docs status changed
12	Announce	X, LinkedIn, GitHub release, and longform copy use final live URLs	Any final URL is still pending

Do Not Proceed

Do not publish an additional npm build before npm pack --dry-run --json is captured from the final release commit.
Do not create or push Claude plugin tags before claude plugin tag .claude-plugin --dry-run passes from the final release commit.
Do not claim an official Codex Plugin Directory listing unless OpenAI documents a public submission path or confirms the plugin has been listed.
Do not announce billing, Marketplace, or native payments until ECC Tools live Marketplace account readback returns ready.
Do not rename the npm package until rc.1 is published and a migration guide maps old install names to new names.
Do not post social copy while any required plugin, video, billing, or outbound URL is still approval-gated.

External Distribution Sources

As of this snapshot, Anthropic documents self-hosted marketplace distribution through GitHub, git URL, remote marketplace JSON, and local path sources. OpenAI documents repo/personal marketplace distribution for Codex and describes an official Plugin Directory, but ECC has not submitted or received an official directory listing in this pass.
